The seamless integration of the architecture and structure of a tall building plays a key role in establishing a recognizable and iconic design. The structural system developed for Shenzhen Rural Commercial Bank Headquarters (SRCBH) utilizes enhanced structural innovations unique to the tower's geometry to improve structural and sustainability performance. SRCBH utilizes a steel diagrid system pulled outside of the enclosure line with diaphragm forces resolved primarily by corner diagonal beams. During the design process the structural systems underwent performance based design and optimization for wind and seismic loading. Resiliency was prioritized for structural design as well as fire resistance. More closely integrating the structure of a building with its architecture and sustainability goals can lead to unique and innovative towers with a timeless expression.

The purpose of this study is to analyze the impact of municipal sustainability policy efforts on citywide $CO_2$ emissions. 25 cities in the U.S.A., which offer data on $CO_2$ emissions and are included in the top 50 largest cities in the U.S.A. according to its estimated population, were selected as study cities. This study utilizes the Sustainable Cities Seriously Index of Portney and selects data for the index at the city level. For analysis, this study employs correlation analysis, and OLS regression analysis. The results show that each city has around 30 sustainability policies and emits $12.76tCO_2$ per year on average. In addition, when the number of sustainability policies increases by one, the amount of $CO_2$ per capita decreases by $0.7tCO_2$. This means that the more cities employ sustainability policies, the less $CO_2$ those cities emit. The results of this study support the idea that active efforts on behalf of municipal governments toward the development of sustainability policies are needed to handle citywide $CO_2$ emissions.

Currently, the environmental improvement project in residential building in Korea is focused on financing. To solve the variety of problems in urban residential areas, the plan need to apply more elements to improve sustainability. Thus, this study aims to find the main strategies to amend sustainability of the environmental improvement project in residential building. To do this, firstly I reviewed previous studies of sustainablity. Secondly I surveyed the planning elements of the three cases in Boksu-Dong District2, Daeseong-Dong District2, and Samsung-Dong District1 in Daejeon. Lastly I used the AHP analysis method and the 5-point Likert-type questionnaire of judged the importance among the plan elements with experts on urban regeneration of which is found through the previous literature review. In conclusion, this study shows the problems of the Residential Environment Improvement Project. Also, I found out the priority of the main planning elements to improve the problems. By contrasting the relative importance among the plan elements with the case study, the result of this study implies the directions of strategies which include the plan elements for responding climate change, residents' participation, and financial support program and system to improve the status of the environmental improvement project in residential building.

The notion of smart cities, presently, is a highly popular topic in urban policy circles. This concept is adopted by many cities across the world-with an aim of increasing urban smartness in various ways and areas. Productivity, innovation, liveability, wellbeing, accessibility, sustainability, governance, planning, and citizen participation are among these areas. Despite good policy intentions, smart city initiatives in practice had only limited impact in delivering the desired urban outcomes. This paper aims to investigate the smart city phenomenon and its planning practice approaches from an evolutionary perspective. The study places smart city plans and strategies of a number of cities across the globe under the microscope. The findings reveal that current smart city efforts are not adequate to combat the challenges of the Anthropocene epoch-that is already upon us. This paper concludes with a consolidated definition of smart and sustainable cities and considerations for moving towards Post-Anthropocentric urbanism-that is truly smart and sustainable urbanism-to avoid an imminent urban ecocide.

On October 3, 1990, Germany achieved peaceful reunification by integrating East Germany into West Germany. Since reunification, the region of East Germany had to have a new value standard in extreme social changes such as legal, political, administrative and spatial amid rapid systemic changes. The purpose of this study is to characterize urban policy related to urban change in DDR in the past 30 years after German unification. In particular, this study examined the change of construction law and Städtebauförderung Program as urban policy. The characteristics of Städtebauförderung programs and urban regeneration are in context with their contents. The characteristics of Städtebauförderung program support program are ultimately aimed at resolving imbalances among cities, improving the quality of life of residents and developing cities with future-oriented sustainability.

Vertical greenery has become an important technological means to improve the ecological environment condition in urban high-density areas, especially in central areas of Chinese cities. The cost of vertical greenery has significantly increased both in the decision-making process of architectural design and in the assessment of the sustainability potential of urban complexes. The estimation and evaluation of the cost of vertical greenery have become important obstacles to multi-party investment in the construction of vertical greenery. Considering the factors of the building typology and full life-cycle cost, this paper constructs an assessment model of vertical greenery in seven types in urban complex, and suggests an optimized approach to vertical greenery in an urban complex.

High-rise as a building typology is gaining popularity in Asian mega-cities, due to its advantages in increasing volumetric density with limited land resources. Numerous factors contribute to the formation of high-rise urban form, from economical and institutional, environmental to socio-political. Environmental concerns over the impact of rapid urbanization in developing economies demand new thought on the link between urban environment and urban form. Outdoor and indoor climate, pedestrian comfort, and building energy consumption are all related to and impacted by urban form and building morphology. There are many studies and practices on designing individual "green" high-rise buildings, but far fewer studies on designing high-rise building clusters from the perspective of environmental performance optimization.. This paper focuses on the environmental perspective, and its correlation with the evolution of the high-rise urban form. Previous studies on urban morphology in terms of environmental and energy performance are reviewed. Studies on "parameterizing" urban morphology to estimate its environmental performance are reviewed, and the possible urban design implications of the study are demonstrated in by the author, by way of a microclimate map of the iconic Shanghai Xiao Lujiazui CBD. The study formulates the best-practice design guidelines for creating walkable and comfortable outdoor space in a high-rise urban setting, including proper sizing of street blocks and building footprint, provision of shading, and facilitating urban ventilation.

With the booming of construction and property industries in China, the demand for high-rises and mega-scale buildings with more integrated building functions, open- and tailor-shaped outlooks, better connections to municipal infrastructures, and higher grades of building importance has been increasing in the past two decades. The seismic design and engineering of such modern mega-buildings face engineering challenges such as hazard mitigation of extreme actions and surroundings, integrated structural frameworks and building skins, complex connections, and overall construction efficiency. It is the work of a new generation of civil and structural engineers to enhance engineering efficiency and achieve overall engineering, environmental, and economical effectiveness for these high-rise projects. This paper elaborates the above topics through case studies on the design and construction of four such developments in China. Some rethinking is conducted on evolution in modern seismic engineering and design through innovation to achieve an acceptable level of overall sustainability and building effectiveness.
